Me and my friends were in one car driving westbound on Walnut Lake Road. I was sitting in the passenger seat and I saw a bright orange glowing light slowly traveling eastbound ahead of us and commented to everyone: "Hey look at that, what is it?" Just then my friend made a left turn into the subdivision to go home. I asked him to stop the car so we can all observe the glowing light. The light was too bright to be an airplane spotlight. It was also traveling too slowly to be an airplane. Then I thought what if it's a helicopter, but I then ruled that out because it looked like it was only about 500-600 feet in the air and I did not hear any sounds that would resemble the sound of a helicopter. I got out of the car just to see if I could hear anything, but the only thing I heard was an unusual very faint mechanical/electronic sound, but I could not confirm this sound was coming from the object. It was also too fast to be a hot air balloon. It slowly passed us and continued heading eastbound in the sky. It was then out of our view because of the trees. Again, it looked like a spherical, bright orange glowing light that looked a little hazy.
